Can’t schools just open 60 (or 30) minutes later if this is a problem? ie: school has winter hours where class starts at 9AM instead of 8:30AM?
I'm not a parent, but I can imagine that if some of my schedule had to change by 30 minutes some months out of the year, I'd find it more inconvenient.
What if school starts/ends at a different time but my job does not?
What if I have a standing appointment at a business that keeps its hours year round that now conflicts with one that changed to winter hours?
It seems more like a different set of problems than a solution.
